How to know when you are pregnant

How do you know whether you're pregnant or not? If you've been trying to get pregnant, there are a few ways to find out whether you're pregnant.

Early pregnancy symptoms

If you notice one or more of these symptoms, it might be an early sign of pregnancy and a good idea to take a pregnancy test.

•      Late period
•      Extreme tiredness
•      Need to wee more often
•      Nausea
•      A metallic taste in your mouth
•      Sensitivity to smells
•      Tender or sore breasts.

How do pregnancy tests work?

Pregnancy tests work by detecting one of the key early signs of pregnancy: a hormone called human chorionic gonadotrophin (hCG). This hormone is only made when a woman is pregnant.

Traces of hCG can be found in the urine from three to four days after implantation, but the concentration needs to continue to build up to a level at which the test can detect it and give a positive result. The best time to take a pregnancy test is from the day that the period is missed. 

Where can I get a pregnancy test?

GP pregnancy test

These tests are either free or a small fee is charged.

You’ll need to take a sample of your urine in a clean container (you can get sample pots from your GP’s surgery). The best time to collect a urine sample is first thing in the morning. This is because levels of hCG will have built up overnight.

If the urine sample is tested on the spot, you probably will be given the result after just a few minutes. You may have to wait up to a few days for the pregnancy test results though.

Home pregnancy test

These tests are available to buy from chemists or supermarkets and enable you to find out if you are pregnant in private after a few minutes.

The tests are considered to be quite accurate, although it is essential that you follow the manufacturer’s instructions carefully.

Choose a kit that you think will be easy for you to use and make sure that you understand what mark or symbol will appear if the test is positive.

Find out more about taking a pregnancy test.

How accurate is the pregnancy test?

It is important to know that whilst a positive result is likely to be accurate, a negative result may be misleading. Some women have a negative result and test again a week later to find that it is positive.

This is due to the levels of pregnancy hormone gradually building up to a level at which they can be detected. If you test yourself very early on and you have a negative result, you should carry out another test in 2-3 days’ time if you have still not had a period.

If you continue to get negative results and still no period, you should consult your doctor.

What should I do if I am pregnant?

Once you get a positive pregnancy test, make an appointment to see your doctor or a midwife.

Tell the doctor’s surgery when you are making the appointment that you have had a positive pregnancy test result as you might need a longer appointment.

      Hi Susan
      Any unprotected intercourse does put you at risk of pregnancy - planned or unplanned. However ,because you had your period after the intercourse, then it is not possible for you to be pregnant from this time.
      Please do use contraception to protect yourself from STI's as well as unplanned pregnancies for your own health in future.

      Hi Lydia, Thank you for your comment.
      If you have been having unprotected sex and you have missed your period then there is every chance that you may be pregnant. Please take a pregnancy test to see if you are pregnant, you can buy tests from any pharmacy or your GP or sexual health clinic should be able to do one for you as well.

      I had unprotected sex in September once, but I don't know if he ejaculated. No protection. My periods are irregular half the time. But they started being steady every month up until that point. Around the time I was supposed to start my period I bled a little bit of red blood, more like spotting and then it stop the same night. Almost a week later the same thing happened. But no.full on period. I've been feeling pressure/heaviness/tightness on my lower stomach and my body been feeling a little off and my lower back has been hurting on and off. I tested a lil over a week ago but came back negative.

    • By Midwife @Tommys on 25 Oct 2018 - 14:00

      Hi L, Thank you for your comment.

      If you have had unprotected sex then there can be a chance that you may get pregnant. If you still haven't had a proper period then do another pregnancy test. If this is still negative and you still think you may be pregnant then please make an appointment to see the GP who will be able to take a blood test for the pregnancy hormone and this should give you a better result.

      Hi Jermicareyes
      It would be a good time for you now that your period is a week late, for you to do a pregnancy test as this will give you a true positive, or true negative result. See the link below for more information on when and how is best to take a pregnancy test.

      I had my period on September 9, I had unprotected sex the cycle. About a week or two I had this unusual feeling like cramps, constipation, back pains so I tested with PT and it showed negative. Am suppose to have my period this months like 7th but I missed it till now, feeling cramps and feeling sick infact am not myself now. Could it be pregnancy. Please help me out. Thanks

    • By Midwife @Tommys on 11 Oct 2018 - 14:14

      Hi Thank you for your comment.

      If you have had unprotected sex and now your period is late then we would suggest that you do another pregnancy test to see if you are pregnant. It may be that you tested too early and this showed up as negative. If you are still getting negative tests and your period doesn't come then please see your GP who can do a blood test for the pregnancy HCG hormone. Hope this helps, Take Care, Tommy's Midwives x

      Hi

      I had my period on the 11th September to the 14th I had sex on the 16th, 17th, 20th 24th 26th and the 27th. My next period should have been 9th October but I haven't seen it yet done a pregnancy test but came back negative

      Thanks

    • By Midwife @Tommys on 11 Oct 2018 - 11:58

      Hi Ka, Thank you for your comment.

      It may be that you are testing too early, this can sometimes be the case that women are pregnant but still getting negative tests. Leave it a few days and test again, if you still don't get a period and you are still getting negative tests then see your GP who can do a blood test for the pregnancy hormone. This will give you an accurate result as the levels of the HCG pregnancy hormone is detected stronger in the blood. Hope this helps, Take Care, Tommy's Midwives x

    • By Eunice75 (not verified) on 2 Oct 2018 - 12:46

      My period was supposed to come out on the 14 of September but it came out on the 16 spotting and later sized on that same day. Then it came back again on the 17 with little dark blood and also seized again, finally it showed up again on the 18 with little blood clot. Now am worried because since then I've been having all these symptoms (1) breast tenderness, vomiting, gas, leg and hand pains, -sex drive, almost all the pregnancy symptoms, please could I be pregnant? Though I've done pregnancy test with PT and it came out negative.

    • By Midwife @Tommys on 4 Oct 2018 - 15:57

      Hi Eunice, Thank you for your comment.
      If you have been having unprotected sex then there could be a chance that you are pregnant if you are having symptoms of pregnancy as well. As this wasn't a normal period for you, then we would suggest doing another pregnancy test or you can go and see your GP who can do a blood test for the pregnancy hormone, then this will give you a clear result if you are pregnant or not.

      I have an IUD and my fiancé and I sexuality active and last month I had a normal period and this month I was 3 days late and quit 2 days early and 2 positive tests even while on period and 5 days after I quit my period it came out negative. Yet I feel fluttering and always hungry, tired, nauseous, could I be pregnant?

    • By Midwife @Tommys on 20 Sep 2018 - 16:24

      Hi Michelle, thank you for your comment.
      It can be possible to fall pregnant when you have an IUD in situ even if the chances are low. If you have had a positive pregnancy test and now it is negative, we would recommend that you go and see your GP about this. Your GP will be able to do a blood test that can test for the pregnancy hormone in your blood, if they suspect a pregnancy then they should refer you for a scan due to you having an IUD. Hope this helps, take care, Tommy's Midwives x

      Hello, I got unprotected sex on August 10th and 11th saw my period 7 days later august 18. Had unprotected sex again September 9th also took a prenatal 5 days before my period is due, no signs of period. What should I do?

    • By Midwife @Tommys on 17 Sep 2018 - 10:21

      Hello, By these dates your period was due just 2 days ago if you have a regular cycle every four weeks. You could try a pregnancy test as many tests now will detect a pregnancy as early as when the period is due.

    • By Saddam (not verified) on 14 Sep 2018 - 23:52

      Hi there,

      I need some good advice: I had unprotected sex with my girlfriend 7 months back and never had sex again. She came to me yesterday saying she’s pregnant with my baby! She even had a period in the meantime so far I know. Is it possible ?? Please help. Thanks

    • By Midwife @Tommys on 17 Sep 2018 - 10:45

      Hello Saddam, Yes this is possible if she is 7 months pregnant. If so she will have the baby in a few weeks time. A normal pregnancy is 40 weeks long. Try just to get the facts very clear before you worry or make any decisions. Take care

    • By kate (not verified) on 14 Sep 2018 - 08:07

      I had sex two days after I saw my period in may but after that I still saw my period with heavy flow the other month. in June I had sex again but I still saw my period with normal flow d next month. but now I don't known why I am feeling movements around my tummy I have never had a missed period
      am I pregnant.

    • By Midwife @Tommys on 14 Sep 2018 - 11:57

      Hi Kate,
      If you continue to have normal periods and a usual cycle then this would mean that you are not pregnant. If you have had sex without contraception since your last period, then there would be a chance of pregnancy, if your next period does not come then I would advise for you to do a pregnancy test.
      Best wishes

    • By Midwife @Tommys on 13 Sep 2018 - 12:53

      Hi Patience, Thank you for your comment.

      From the dates that you are given it looks like you have sex around ovulation but if you are having unprotected sex at anytime in your cycle you have a chance of getting pregnant. You need to wait until you miss a period and then do a pregnancy test. Hope this helps, good luck, Tommy's Midwives x

    • By Midwife @Tommys on 7 Sep 2018 - 13:06

      Hi Vivian,
      If you have had intercourse without contraception and there would be a chance that you are pregnant. If your period does not come when due then I would suggest for you to take a pregnancy test to see if you are pregnant. In the meantime it would also be important for you to be taking a folic acid supplement if you think you may be pregnant.

      Hi Ann
      Your will need to do a pregnancy test to be sure. This is best done a week after your period is due for the most accurate results. Best to do the test with the first wee of the day for highest hcg content in the urine

      Hi I’m pregnant but the cramping it’s keeping me awak.! Keep waking up in sweats in middle off night.!! Xx.
      Keep weeing a lot plus number two a lot.!
      For the past five days.!
      I’m worried it may hurt the baby even tho I’m only 6 weeks .!
      What can I do.? I have a scan booked in 2moro but the heat and cramps are unbearable...

    • By Midwife @Tommys on 15 Aug 2018 - 14:47

      Hi Sharon
      You need to go to your GP for an urgent review ASAP!
      If they cannot see you as an urgent appointment, then you should go to a&e minors. You could have an infection if you are sweating that much and feeling that unwell for so long with an upset stomach. The abdominal pain is also a concern which needs to be addressed urgently. So please be seen as soon as possible. Take good care of yourself

      I had unprotected sex on 5/17
      I took a pregnancy test 1 week later and it came up negative
      I started my period the day after and bled for 6 days
      I had a second period on time on 6/24 and again bled for 6 days
      Its now been 43 days since the last day of my previous period. I've been having abdominal pains but its not like cramps and I haven't had any other symptoms. But is it possible I could still be pregnant even after having my period twice?

    • By Midwife @Tommys on 15 Aug 2018 - 14:43

      Hi Lizzy J
      It sounds very unlikely that you are pregnant as you have had x2 periods and a negative pregnancy test.
      You should go to your GP who can do a blood/urine pregnancy test again to be 100% sure if you feel that this is a sudden change for you. If you are not pregnant, then you may need further gynae investigations which your GP can refer you for.

Can u please tell that am i pregnant??? I had home urine test twice and it came out to be negative. My periods are due in the last month of august. Please tell if am pregnant?? Or not .. there is not to worry about

    • By Midwife @Tommys on 14 Aug 2018 - 12:20

      Hi, please take a further pregnancy test when your period is due. It may be that you have tested too early and the other symptoms aren't related to pregnancy.
      Even if your partner did not ejaculate inside you this is not a reliable form of contraception so if you don't want to get pregnant at the moment you need to consider other forms of contraception so you don't need to worry. If you need further advice get back in contact.

      Im experiencing abdominal cramps for about 7 days, im not sure if its implantation cramps or just PMS. I dont know what to do because I've read online that implantation cramps happen for about 1 to 3 days and when it exceeded it might be just pms but i haven't had my monthly menstruation for july and im stressed out because it's already August when i expected to have my period on july 21. Is it possible that i am pregnant or just missed my monthly period?
